The test we strongly recommend for most new participants is
But if cost is a serious issue for you, the "basic test" of
12 markers goes for only $54.00.
The 12-marker test is almost always adequate for "disproving" relationships.
In other words, if it shows no match with another
individual, then you can be virtually certain you aren't
related to him.
On the other hand, this test often generates spurious
or "false positive" matches. So if you test only for 12
markers and then find a match, you'll usually need an
upgrade to 37 to determine if your match is
genuine -- and your upgrade will entail an additional
delay of four to eight weeks, not to mention a
considerable cost premium.
The 67-marker test is seldom
useful unless you have at least one or two matches who
have also tested for 67 markers. But in any event, if you
merely have a "scientific" curiosity about the results, then we
won't discourage you from the 67-marker test.
Finally, if you
live outside the USA, please note that there will be an
additional mailing charge of USD 2.00.
